I have two dropdown nodes, one on one tab, and the other on a second tab. If I manually inject options into them to setup the dropdown items everything works as expected. When I automatically inject the same items, they don't properly display their dropdown items.
The attached flow is set to automatically inject the items. After I deploy, and click on the tabs, I don't see the two items on each dropdown list as expected. If I press the manual inject buttons, everything works.
